Answer:
C, 20 units
Step-by-step explanation:
We see that both angles QRS and QTR are 90 degrees. In addition, angles SQR and RQT are equivalent (because they're both angle Q).
By AA Similarity, we know that triangle QTR is similar to triangle QRS.
With this similarity in mind, we can look at the ratios of corresponding lengths to set up a proportion. QR from triangle QTR is the hypotenuse, and it corresponds to hypotenuse QS from triangle QRS. So, we can write the ratio x/(9 + 16) = x/25.
Now, we see that long leg QT of triangle QTR corresponds to long leg QR of triangle QRS. So, another ratio we can write is: 16/x.
Finally, we set these two ratios equal to each other:

Cross-multiplying, we get:
.
Thus, x =
. The answer is C, 20 units.
Hope this helps!
Answer:
Probability of each situation is 1/3 .
Step-by-step explanation:
There are 3 possibilities
1- Train will arrive early
2- Train will arrive on time
3- Train will arrive late
Formula for Probability of event a is = n(a)/Sum of events
In this case sum of events = 3
So
Probability of early arrival = 1/3
Probability of on time arrival = 1/3
Probability of late arrival = 1/3
